8-\left(3x-5x-3\right)=6x-\left(4x-7+x\right)
Hei kimi i te tauaro o 5x+3, kimihia te tauaro o ia taurangi.
8-\left(-2x-3\right)=6x-\left(4x-7+x\right)
Pahekotia te 3x me -5x, ka -2x.
8-\left(-2x\right)-\left(-3\right)=6x-\left(4x-7+x\right)
Hei kimi i te tauaro o -2x-3, kimihia te tauaro o ia taurangi.
8+2x-\left(-3\right)=6x-\left(4x-7+x\right)
Ko te tauaro o -2x ko 2x.
8+2x+3=6x-\left(4x-7+x\right)
Ko te tauaro o -3 ko 3.
11+2x=6x-\left(4x-7+x\right)
Tāpirihia te 8 ki te 3, ka 11.
11+2x=6x-\left(5x-7\right)
Pahekotia te 4x me x, ka 5x.
11+2x=6x-5x-\left(-7\right)
Hei kimi i te tauaro o 5x-7, kimihia te tauaro o ia taurangi.
11+2x=6x-5x+7
Ko te tauaro o -7 ko 7.
11+2x=x+7
Pahekotia te 6x me -5x, ka x.
11+2x-x=7
Tangohia te x mai i ngā taha e rua.
11+x=7
Pahekotia te 2x me -x, ka x.
x=7-11
